Abstract

PURPOSE
To analyze the results of treatment in pure anisometrpic amblyopia with unilateral visual acuity of 0.1 or worse. METHODS: The major eligibility criteria included pure anisometropic amblyopia with age <10 years, best-corrected visual acuity 0.1 or worse in the worse eye and 0.5 or better in the good eye after the wearing of optimal spectacle correction for a minimum of 4 weeks, and the minimum follow-up was 6 months. Twenty-one patients were selected and we analyzed the age at the amblyopia treatment, the type and degree of anisometropia, and the final visual acuity after treatment for visual improvement. Successful treatment was defined as a final visual acuity of 0.3 or more. RESULTS: The mean age at treatment was 5.2 years. The types of anisometropia were hypermetropic in 14 patients, astigmatic in 4, and myopic in 3. The mean duration of treatment of amblyopia was 16 months, and 13 of 21 children with pure anisometropic amblyopia achieved 0.3 or better. The age at treatment was younger and the compliance rate was higher in the success group than in the failure group. CONCLUSIONS: The most common type was hyperopic in the pure anisomteropic amblyopia. Compliance and age at treatment were significantly related to best visual acuity attained in pure anisometropic amblyopia with unilateral visual acuity of 0.1 or worse.
